KINGLED KP3000 LED Grow Lights
$129.99 price checked August 2026
If you need to cover a 4×4 ft grow tent area, this 300w light is the right choice to price-check.
Where the KINGLED KP3000 Fits
The KINGLED KP3000 LED Grow Light is for indoor hobbyists who need a 300w output to cover a 4×4 ft area effectively.
Inconsistent light distribution often leads to “dead zones” where plants fail to thrive, resulting in stunted growth and uneven harvests. Ensuring every leaf receives adequate PAR is the primary challenge for indoor growers trying to maximize their yield.
The KINGLED KP3000 LED Grow Light addresses this by providing a full spectrum of light across a 4×4 ft coverage area. With 1620 LEDs, including specific 460 nm blue and 660 nm red wavelengths, it provides the balanced output needed for various growth stages.

The Short Answer on the KINGLED KP3000
Best for: you need a 300W light to provide sufficient PPFD for a 3x3ft canopy during the flowering stage.
The KINGLED KP3000 is a solid choice for this setup at $129.99.
- Pro: The 300W power output meets the minimum threshold for high-intensity flowering.
- Pro: It features 630 yellow and 630 white LEDs to provide a full spectrum.
- Pro: The 4×4 ft coverage area accommodates standard grow tent sizes.
- Con: The Yield LEDs do not reach the Samsung LM301H standard for maximum efficiency.
- Con: The 300W power limits the fixture to smaller spaces and cannot support large-scale commercial greenhouse production.
Don’t buy this if: you require a light that provides a PPFD over 900 µmol/m²/s for professional-grade fruit production.
Price assessment: At $129.99, this light is priced fairly for a 300W fixture with a 4.5 rating.
Green Writer score: 8.5/10 (data-driven – see “How we picked” above)

The Specifications That Matter
| Light Source Wattage | 300 Watts |
| Light Output Maximum | 8200 Lumens |
| Coverage Area | 4×4 ft |
| Color Temperature | 3000k to 5000k |
| Voltage | 110 Volts |
| LED Count | 1620 LEDs |
| Item Weight | 9 Pounds |
The 300 Watts of power output meets the 300W per fixture threshold required to provide sufficient PPFD for a 3x3ft canopy during the flowering stage.
Where this sits in the buyer data: Among the 89 products screened for this category, this one’s 4.5 rating places it #24, on 5,341 ratings – above the 456-rating median of that group, so the average rests on more feedback than most of its comparables. On price it undercuts 60 of them.
Before You Buy: KINGLED KP3000 Checklist
The first thing to check is your grow tent or area dimensions to ensure the light’s footprint matches your space.
- ☐ Confirm the coverage area — 4×4 ft
- ☐ Verify the power consumption — 300 watts
- ☐ Check the diode count — 1620 LEDs
- ☐ Measure your power source capacity — 300W per fixture
- ☐ Budget for the unit cost — around $129.99
You should not buy the KINGLED KP3000 if your grow area exceeds 4×4 ft, as the light may create dead zones or insufficient PPFD in larger spaces.
Performance: What the Specs Deliver
Full Spectrum Light Distribution
The KINGLED KP3000 provides a full spectrum of light including 460 nm blue light and 660 nm red light. This specific spectral range supports the various stages of plant development, from early vegetative growth to the flowering stage. Because the light covers the 3000k to 5000k white light range, you can expect consistent coverage for indoor plants and hydroponics.
The 1620 LEDs are balanced with 180 red, 180 blue, 630 white, and 630 yellow diodes. This distribution ensures that you do not face the spectral imbalances that cause stretching or poor fruit set. The high PAR output from these diodes provides the intensity required for a 4×4 ft coverage area.
Three Growth Mode Versatility
The KINGLED KP3000 features three specific modes: Veg, Bloom, and Veg & Bloom. The Veg mode prioritizes the 460 nm blue light to encourage leafy growth, while the Bloom mode shifts the output toward the 660 nm red light to support flower and fruit production. The Veg & Bloom mode provides a balanced output for plants that require consistent growth throughout their life cycle.
You can switch between these modes to match your specific plant’s needs without changing your hardware setup. Because the data does not specify the exact wattage shift between these modes, you should verify the specific intensity levels of each setting in the user manual before starting a new crop.
High Lumen Maintenance
The KINGLED KP3000 is rated for 8200 lumen maintenance. This rating indicates the light’s ability to retain its brightness over time, which helps prevent the dimming caused by thermal throttling or diode degradation. High lumen maintenance ensures that your plants continue to receive the necessary PPFD levels as the fixture ages.
Consistent light output is essential for maintaining growth rates in a 4×4 ft grow tent. By maintaining its lumen output, the KINGLED KP3000 helps you avoid “dead zones” where plants might otherwise fail to thrive due to a drop in light intensity over the season.

Is the KINGLED KP3000 Right for You?
The KINGLED KP3000 suits 5 kinds of buyer and is the wrong choice for 3 jobs, listed below with the reason for each.
Who the KINGLED KP3000 is for, and what it does well
Who the KINGLED KP3000 suits
- Home cannabis cultivators — the 4×4 ft coverage area and 300w power output fit standard small grow tents
- Hydroponic hobbyists — the high PAR output and full spectrum LEDs are designed for water-based nutrient delivery
- Indoor herb gardeners — the three modes (Veg, Bloom, Veg & Bloom) allow for different growth stages of culinary herbs
- Small-scale boutique growers — the 660 nm red and 460 nm blue light wavelengths are optimized for high-yield flowering
- Apartment plant collectors — the 300w power consumption provides sufficient light for indoor foliage without industrial scale requirements
What the KINGLED KP3000 handles well
- Growing flowering plants — the 660 nm red light and Bloom mode
- Seedling propagation — the 460 nm blue light and Veg mode
- Full-spectrum indoor gardening — the 1620 Yield LEDs and full spectrum coverage
- Small greenhouse setups — the 4×4 ft coverage area
- High-intensity indoor farming — the high PAR output
What the KINGLED KP3000 is the wrong choice for
- Large commercial greenhouses — the 4×4 ft coverage area is too small for industrial scale
- High-intensity professional flower farms — the 300w power output is insufficient for large-scale commercial production
- Deep-canopy orchard lighting — the 4×4 ft coverage area limits light penetration for large trees
What to budget alongside the KINGLED KP3000, and what to skip
Worth buying at the same time
- 4×4 ft grow tent — the coverage area is specifically designed for this size
- Heavy-duty power cable — the 300 watts power consumption requires a reliable electrical connection
- Adjustable hanging hooks — the 300w unit requires a mounting system to position the light over the plants
- Timer switch — the three modes require a scheduled cycle to manage Veg and Bloom stages
- Reflective Mylar sheeting — the 4×4 ft coverage area benefits from maximizing the high PAR output
What you can skip
- Separate blue and red bulbs — the 1620 Yield LEDs already include 180 red and 180 blue diodes
- Full spectrum light strips — the 3000k to 5000k white light and full spectrum specs cover these needs
- Low-lumen bulbs — the 8200 lumen maintenance spec makes lower-output alternatives unnecessary
